      Is the inspection result normal? 

      YES: GO TO 5.

      NO: Replace the fuse after repair the applicable circuit.

5. CHECK ECO MODE SWITCH ILLUMINATION POWER SUPPLY CIRCUIT 
   1. Disconnect IPDM E/R harness connector E45. Refer to "WIRING DIAGRAM ".
   2. Check the continuity between IPDM E/R harness connector and ECO mode switch harness connector.

      +		-		Continuity
      IPDM E/R		ECO mode switch
      Connector	Terminal	Connector	Terminal
      E45	33	M82	1	Existed

   3. Also check harness for short to ground.

      Is the inspection result normal? 

      YES: Perform IPDM E/R auto active test and check tail lamp relay operation. Refer to "DIAGNOSIS DESCRIPTION " (with intelligent key), "DIAGNOSIS DESCRIPTION " (without intelligent key).

      NO: Repair or replace error-detected parts.

6. CHECK GROUND CIRCUIT 
   1. Turn OFF the headlamp.
   2. Turn ignition switch OFF.
   3. Check continuity between ECO mode switch harness connector terminal and ground.

      +		-	Continuity
      ECO mode switch
      Connector	Terminal
      M82	4	Ground	Existed

      Is the inspection result normal? 

      YES: Check intermittent incident. Refer to "INTERMITTENT INCIDENT ".

      NO: Repair or replace error-detected parts.

7. CHECK ECO MODE SWITCH CIRCUIT 
   1. Turn OFF the headlamp.
   2. Turn ignition switch OFF.
   3. Disconnect ECO mode switch harness connector.
   4. Turn ignition switch ON.
   5. Check voltage between ECO mode switch harness connector terminals.

      ECO mode switch			Voltage (Approx.)
      Connector	+	-
      	Terminal
      M82	6	8	5 V

      Is the inspection result normal? 

      YES: GO TO  11.

      NO: GO TO 8.

8. CHECK GROUND CIRCUIT 
   1. Turn ignition switch OFF.
   2. Check the continuity between ECO mode switch harness connector and ground.

      +		-	Continuity
      ECO mode switch
      Connector	Terminal
      M82	8	Ground	Existed

      Is the inspection result normal? 

      YES: GO TO 9.

      NO: Repair or replace damaged parts.

9. CHECK CIRCUIT BETWEEN COMBINATION METER AND ECO MODE SWITCH-1 
   1. Disconnect combination meter harness connector M38.
   2. Check continuity between combination meter harness connector terminal and ECO mode switch harness connector terminal.

      +		-		Continuity
      Combination meter		ECO mode switch
      Connector	Terminal	Connector	Terminal
      M24	25	M82	6	Existed
